IMPROVEMENT IN STILLS FOR ALCOHOLIC SPIRITS.

The Schedule referred to in these Letters Patent vanzi making part of theA same.

To 'whom it may concern:

Be it known that we, WILLIAM RoBsoN and Gnone YV. ROBSON, both of Cincinnati, Hamilton county, Ohio, have invented a certain new and useful Improvement in Stills; and we hereby declare the following to be a full, clear, and exact description thereof, .reference being had to' the accompanying drawings, making part ot" this specification.

This invention has for its object the economical, rapid, and eiiective manufacture of superior prooispirit, by double but continuous distillation, rst, with steam alone, forming low-wine, and, secondly, with iire, or 'with steam and tire cfnnbined, forming finished spirit; and

The iirst part of our inveutionconsists in the co1 nbination, with a customary stean'i-heated doubling-still, of' a copper still, so constructed and arranged as to receive heat from a furnace beneath it, either in conjunction with a steam-heater, or otherwise' secondly, automatic and other contrivances, for maintaining a proper supply of low-wine in the finishing-still, and the proper' observation and distribution ofthe low and highwines, as the work progresses.

The accompanying drawing is a partially-sectioIiized elevation ot' a distilling-apparatus, embodying our iuvention, the different vessels being arranged in one plane, for convenience of illustration.

IVe employ, in our process, a common steam-heated distillery, hawng the customary steamgenerator or boiler' A, wort-tun and pump B b, steam-heated still C, doubler I), flake-stand or worm-tub E, and low-wine worm F. v

Proceeding from the bottom of the vstill (l, is the Ycustomary slop-pipe c.

The low-wine worm F discharges into a tester-glass, H, which empties into the close tank or reservoir 1,

tfrom whose bottom a pipe, J, leads into the upper part ofa copper still, L, having beneath it a furnace, M, and, traversing its` lower portion, a steam-pipe, N, having, outsideot' the still-body, a discharge-cock, n.

Leading from the bottom ofthe still-body, isa cock, l, having a lock', o, which may be luider control of the superintendent or of the Government supervisor.

I is a pipe, from the top ofthe copper still L, which pipe enters the bottom ofthe drum K, from whose upper portion there emerges another pipe, that, in the form of a worm, P', t averses the same flake-stand that contains the low-wine worm F, and said pipe or worm I discharges into a tester-glass, Q, proiided with a two-way cock, R, for discharging into the low-,wine receiver S, or into the high-wine receiver T, according to the observed condition of the liquor in the tester.

From the low-wine receiver S, the liquor is, from time to time, returned to the doubler D, by means of pump U, and, from the high-wine receiver T, is forwarded to the whiskey-house tank Y, by means' oi' pump X is ages-veut, from tail of worm, in connection with which a customary water-trap, not shown, is employed.

A ball-cock, Y, to the delivery-end of the pipe J, acts automatically, to maintain the propersupplyot' liquor in the copper still, the level and temperature of said liquor being made known by any customary indi- -cators.

` The drum K may be provided with slides, for the' support of removable colanders, 7:, to hold juniperberries, coriander-seeds, peach-pits, or other iiavoringmatters. By a removable head or door, Z, access is had to the colanders 7;.

The chief use of the steam-heater N is to start the boiling-action inthe finishing-still, at the commencementot' a run, so as to save time,'after which it 'may be shut ofi'.

IVe have described the preferred form of oui` invention, but reserve the right to vary the same in non essential particulars. For example, the drum K may be omitted, and the two worms may have separate tubs, it' desired. A meter may be used in place ot' i.r in conjunction with the tester Q. Instead ofthe twoway cock, there may be a separate cock to each receiver', and the steam-pipe or coil maybe omitted from the finishing-still.

We claim herein as new, and of our inventionl. The described double distillation, rst, with the ordinary .steam-distillery, and, secondly, with the finishing-stili Lof copper, heated by tire, or by tire and steam combined.

2. The close low-wine tank or reservoir I, between the steam-distilling worm-tub and the copper or finishing-still, to receive the low-wine. from the steamor other primary distillation, and to deliverI the same into the said finishing-still.

3. 'hile disclainiing the general principle of introducing pu'riiying or Havering-matters between the still and condenser, we claim the construction and arrangement ofthe drum K, and remo vable colanders lo 7.', as and for; the purposes herein shown and described.

4.' The low-wine worm F, reservoir I, finishing-still L, high-wine worm I", tester or separator Q, and low and highewine receivers S and T, with their described or equivalent accessories, the wholeheilig combined and operating substantially as set forth.

In testimony of which invention, we hereunto set our hands.
